Aedes aegypti ndiyo yekutanga vector yeakawanda arboviruses (senge dengue, chikungunya, uye Zika) izvo zvinokonzeresa kuputika kwechirwere chevanhu munzvimbo dzinopisa uye dzinopisa. Kutonga kwehosha uku kunovimba nekudzora mavector, kazhinji nenzira yemishonga yekuuraya zvipembenene inonangana nehumhutu hwechikadzi. Zvakadaro, kufukidzwa kwenzvimbo uye kuwanda kwekupfapfaidza kunodiwa kuti zvinyatsoshanda hazvina kujeka. Muchidzidzo chino, tinotsanangura mabatiro ekumwaya mudzimba nemishonga yepyrethroid inonzi Ultra-low volume (ULV) pahuwandu hwemosquito hwemhuri yeAedes aegypti.
Mhedzisiro yedu inoratidza kuti mukati-mudzimba kudzikira muAedes aegypti zvakanyanya nekuda kwekupfapfaidza kunoitika mukati meimba imwe chete, pasina imwe mhedzisiro kubva mukupfapfaidza mudzimba dzakavakidzana. Kupfapfaidza kushanda kunofanirwa kuyerwa maererano nenguva kubva pakapfapfaidzwa kekupedzisira, sezvo tisina kuwana mhedzisiro kubva kupfapfaidza dzinotevedzana. Zvichienderana nemhando yedu, tinofungidzira kuti kushanda kwepfapfaidzo kunodzikira ne50% mazuva angangoita 28 mushure mekupfapfaidza.
Kudzikira kweAedes aegypti kuwanda mukati meimba kwainyanya kutariswa nehuwandu hwemazuva kubva pakupedzisira kupfapfaidza mumba iyoyo, zvichiratidza kukosha kwekupfapfaidza kufukidzwa munzvimbo dzine njodzi huru, nekupfapfaidza frequency zvinoenderana nehutachiona hwemunharaunda.
Muchidzidzo ichi, takashandisa dhata kubva mumiyedzo mikuru miviri yemumunda yekupfapfaidza yakaderera-yakaderera mukati meimba yepyrethroid muguta reIquitos, mudunhu rePeruvia reAmazon kufungidzira kukanganisa kwekupfapfaidza kwepamusoro-soro pamunhu wega wega aedes aegypti mosquito huwandu mukati meimba, ichipfuura miganhu yeimba imwe chete. Tsvagiridzo yapfuura yakafungidzira mhedzisiro yeakanyanya-yakaderera vhoriyamu kurapwa zvichienderana nekuti dzimba dzaive mukati kana kunze kwenzvimbo yakakura yekupindira. Muchidzidzo ichi, tinovavarira kupatsanura marapirwo anoitwa padanho repamusoro remhuri yega yega kuti tinzwisise kubatsirana kwekurapa kwemumba zvichienzaniswa nemishonga yemudzimba dzakavakidzana. Nekufamba kwenguva, takafungidzira kuwedzera kwekuita kwekudzokorora kupfapfaidza tichienzanisa nekupfapfaidza kwazvino paAedes aegypti kuderedzwa mudzimba dzehuku kuti tinzwisise kuwanda kwekupfapfaidza kunodiwa uye kuongorora kuderera kwekuita kwepfapfaidzo nekufamba kwenguva. Ongororo iyi inogona kubatsira mukuvandudza nzira dzekudzora vector uye nekupa ruzivo rweiyo parameterization yemamodheru kufanotaura kushanda kwavo.
Mhedzisiro yekufarira inotsanangurwa sehuwandu hwehuwandu hwevanhu vakuru Aedes aegypti yakaunganidzwa paimba imwe neimwe i uye nguva t , iyo inofananidzwa muhuwandu hweBayesian framework uchishandisa yakaipa binomial kugovera kuverengera pamusoro pekuwedzera, kunyanya sezvo nhamba huru yeAedes aegypti yevanhu vakuru yakaunganidzwa. Tichifunga kusiyana kwenzvimbo uye magadzirirwo ekuedza pakati pezvidzidzo zviviri, mhando dzese dzevamiriri dzakaiswa kune S-2013 neL-2014 datasets, zvichiteerana.

Huwandu hweumhutu hweAedes aegypti mumba hunoenderana zvakanyanya nenguva yakapfuura kubva pakupfapfaidza kwekupedzisira mumba iyoyo.
Chinhu chakakosha chekudzidza kwedu ndechekuti isu hatina kudzora kwezera revakuru veAedes aegypti mosquito yakaunganidzwa. Ongororo yapfuura yezviedzo izvi [14] yakaratidza kuti kugoverwa kwezera kwevakadzi vakuru vaiwanzove vadiki (yakawedzera chikamu chevakadzi vasina nulliparous) munzvimbo yeL-2014 yekupfapfaidza zvichienzaniswa nenzvimbo yebuffer. Nokudaro, kunyange zvazvo tisina kuwana rimwe rinotsanangura basa rekupfira zviitiko mumhuri dzakapoteredzwa paAedes aegypti yakawanda muimba yakapiwa, hatigoni kuva nechokwadi chokuti hapana migumisiro yenharaunda paAedes aegypti yehuwandu hwehuwandu hwehuwandu hwehuwandu hwehuwandu hwehuwandu hwehuwandu hwehuwandu hwehuwandu hwehuwandu hwehuwandu hwehuwandu hwehuwandu hwehuwandu hwehuwandu hwehuwandu hwehuwandu hwehuwandu hwehuwandu hwehuwandu hwehuwandu hwehuwandu hwehuwandu hwehuwandu hwehuwandu hweAedes aegypti hunowanzoitika.
Zvimwe zvipingamupinyi zvekudzidza kwedu zvinosanganisira kusakwanisa kuzvidavirira pakupfapfaidza kwechimbichimbi neBazi Rehutano, kwakaitika mwedzi ingangoita 2 mwedzi isati yaitwa yeL-2014, nekuda kwekushaikwa kweruzivo rwakadzama pamusoro penzvimbo uye nguva. Ongororo yapfuura yakaratidza kuti masprayiri aya aive nemhedzisiro yakafanana munzvimbo yese yekudzidza, achigadzira yakajairika baseline level yeAedes aegypti density; kutaura idi, panguva apo kupfapfaidza kwokuedza kwakatanga, vanhu veAedes aegypti vakanga vatanga kunaya . Uyezve, kusiyana kwemigumisiro pakati penguva mbiri yekuedza inogona kunge yakakonzerwa nekusiyana kwekugadzirwa kwekudzidza uye kukanganisa kwakasiyana kweAedes aegypti kune cypermethrin, neS-2013 inonzwisisika kupfuura L-2014.
Chekupedzisira, mhedzisiro yedu inoratidza kuti mhedzisiro yekupfapfaidza mumba yaingogumira kumhuri kwakaitika kupfapfaidza, uye kuti kumwaya mudzimba dzakavakidzana hakuna kuwedzera kuderedza Aedes aegypti. Humhutu hweAedes aegypti hunogona kuramba huri pedyo kana kuti mukati medzimba, huchiungana mukati me10 m uye huchifamba avhareji yedaro re106 m. Saka, kupfapfaidza nzvimbo yakatenderedza imba kunogona kusave nemhedzisiro yakakura pahuwandu hweAedes aegypti mumba iyoyo. Izvi zvinotsigira zvakaonekwa kare kuti kumwaya mvura kunze kana kutenderedza imba hakuna zvakunoita . Zvisinei, sezvataurwa pamusoro apa, panogona kunge kune masimba emunharaunda paAedes aegypti huwandu hwevanhu, uye muenzaniso wedu hauna kugadzirirwa kuona migumisiro yakadaro.
Takatorwa pamwechete, mhedzisiro yedu inoratidza kukosha kwekusvika imba yega yega iri panjodzi huru yekutapurirana panguva yekuputika, sezvo dzimba dzisina kupfapfaidzwa nguva pfupi yadarika hadzigone kuvimba nekupindira kwepedyo kana kupindira kwakawanda kwakapfuura kuderedza huwandu hwazvino hweumhutu. Nemhaka yokuti dzimwe dzimba dzakanga dzisingasvikike, kuedza kwokutanga kupfapfaidza nguva dzose kwaiguma nokufukidzwa zvishoma. Kushanya kunodzokororwa kumhuri dzakashaikwa kunogona kuwedzera kuvharirwa, asi kudzoka kunodzikira nekutenderera kwega kwega kwekuedza uye mutengo wemhuri unowedzera.
